I have a web application written in AngularJS that uses the OWIN middleware for OAuth 2 authentication and ASP.Net 4.5 Web API to provide data access.
The entire app runs fine locally when launched directly from Visual Studio 2015 Community (using the default of Cassini). However, when I publish it to IIS 8 on my local server that is running Windows Server 2012 I get 404 errors for any URL that I attempt to request from Web API as well as the OAuth token URL endpoint.
I have confirmed via logging that the OWIN startup class is being started and running successfully. See the end of the post for the code from both this startup class and my Web API config class.
I am entirely out of ideas on where to go next. What do I need to do to get this thing working? Any help is greatly appreciated.
I have tried the following with no luck as to a resolution:
- Make sure that
Microsoft.AspNet.WebApi.WebHosthas been added via Nuget and is present in the bin folder in the sites folder under wwwroot as suggested at Owin Middleware results in 404 on server - Checked that my app pool is set to v4.0 and integrated mode as also suggested in the link from #1
- Adding
runAllManageModulesForAllRequests="true"to the modules section of my Web.config as suggested at How to get IIS to recognize OWIN startup class? - Adding
app.UseStageMarker(PipelineStage.MapHandler);to the end the OWIN startup class as suggested in the post from #3 - Adding the new handler
<add name="Owin" verb="*" path="*" type="Microsoft.Owin.Host.SystemWeb.OwinHttpHandler, Microsoft.Owin.Host.SystemWeb" />specifically for OWIN as suggested at OWIN WebApi project on IIS 10 gives 404 on all operations
Update 1
I realized that I inadvertently neglected to mention in the orginal post that IIS is using its default settings and I'm able to load the home page of the site and other pages. The requests to get the data via Web API or login just bomb with 404s. Will update with the modules installed in IIS when possible later today.
